• Specifications: • Based on the Jaguar CPU architecture from AMD • Consists of 2 -64 quad core modules (8 cores total) • 32 KB L1 instruction and 32 KB data caches for each core • One 2 MB L2 cache per four cores • Share cache between cores • Frequency of 1.6 GHz JAGUAR CPU

• From AMD • Succeeded the Bobcat family • L1 cache includes parity error detection • 2 way superscalar • Out-of-order execution • Speculative execution • Instruction set: • AMD 64 • Complex Instruction Set Computing (CISC) JAGUAR CPU (continued) JAGUAR CPU (continued)

• Improvements over Bobcat: • 10% increase in clock frequency • 15% improvement in IPC • Doubled bandwidths for load and store units • Smaller core size • FPU data path width increased to 128 bits • Up to 4 cores GPU

• Customized version of AMD’s 7870 GPU with 2 compute unit disabled • GPU Clock: 800 MHz • 18 compute unit: • 64 cores per compute unit • 1152 cores total COMPUTE UNIT

• AMD’s latest processing architecture : • Heterogeneous System Architecture • Bridges the gap between CPU and GPU cores • Allows the CPU and GPU to share workloads and memory • More efficient way to accelerate application while delivering great performance AMD 7870 GPU

• Engine Clock: 1000 MHz • 2 GB DDR5 memory • Memory clock: 1200 MHz • 20 Compute Units • PCI-e 3.0 MEMORY

• 8 GB of GDDR5 unified system memory • Max frequency of 2.75 GHz • GDDR5: • Based on DDR3 SDRAM • Uses 8-bit wide pre-fetch buffers • Bandwidth of 176 Gb/s • Bus Width: • 256 bits FUTURE OF THE PLAYSTATION

• Just Speculations: • PS5 release in 2020 • Optical computing for the CPU • 3D Xpoint or 3D Stacked RAM • GPU: • 4K UHD
